The Times's editorial board, which has a few questions for the DPD about how this "noxious practice" was allowed to go on for so long without detection, could not agree more:

This is a country that has repeatedly gone overboard in its reaction to
immigrants who don't speak the common tongue, but the mind still reels
at this one. Where were these officers' supervisors, who presumably
reviewed and approved each of these tickets after they were filed?
Where were the judges who must have encountered these language
offenders in traffic court? ... There is no question that the efforts to [have local peace officers enforce federal immigration policies] so have been marred by poor
training, racial profiling and other abuses -- and widespread fear in
the communities that the police are sworn to protect. If there is any
remaining doubt, just take a look at what happened in Dallas.
